Calculate P(B U A), given that P(A) = 0.75, P(B) = 0.6 and P(B Intersect A) = 0.55. The answer should be 0.85. In lecture of "Additive Law", the answer of this question is given as 0.80. Please clarify.

Hey Chintan, Using the additive law, P(A) + P(B) - P(AnB) = 0.75 + 0.6 - 0.55 = 1.35 - 0.55 = 0.8. Best, 365 Vik
